A novel coating technology is proposed for the protection of naval weapon components. Diamondlike nanocomposites constitute a new class of materials that exhibit unique combinations of technologically interesting properties including high adhesion to vertually any substrate (including metals, crystalline and glass dielectrics, plastics), excellent chemical and diffusion barrier properties, good ha ...

The standard technique for the recording of telemetry data in range operations has been instrumentation tape recording. This has provided the capability for recording data at high data rates for extended periods of time. While convenient for recording, this technique suffers drawbacks in processing and playback of the data. Due to the serial nature of the medium, no capability exists for near-re ...

Astralux is developing heterobipolar transistors (HBT) using a SiC base. This device operates above 500 C with a current gain in excess of 100. Most of the effort went into design, technology, and characterization of these devices. To make the HBT into a commercial product, the technology of contacts and packaging must be developed. This proposal considers a joint project with NAWCAD and a pac ...

Astralux, having recently made the first transistor structure to operate above 500 C with a current gain exceeding 100, proposes to explore the limitations of the transistor's power handling capability. At room temperature, this transistor carries a current density one order of magnitude higher than commercial silicon power transistors. Also it is proposed to study the maximum frequency at which ...

This proposal presents a unique and innovative approach to designing and realizing an integrated aperture made up of a wideband, nominally 0. 5 to 2. 0 GHz, array and a precision X-band array. AAEC proposes to realize the wideband element by a rigid wire structure. Second, AAEC proposes a design tool based on well validated computational electromagnetics codes that actually relate changes in the n ...

The shallow-water and surf-zone mine clearance mission is being addressed by existing U. S. Navy programs. The clearance of manmade obstacles from the surf-zone and beach comprises an equal priority for the amphibious assault mission in littoral warfare. The effectiveness of non-explosive obstacles to deter a U. S. amphibious assualt mission has been increased somewhat by the introduction o ...
